A Chinese restaurant owner offers customers the chance to claim a 20-yuan (HK$23) banknote, pinned to the striped uniforms of waiting staff, if they are dissatisfied with the service, mainland media reports.

The restaurant, called Go To My House, in the city of Taizhou, Zhejiang province, which charges diners an average of 53 yuan per head – including a service fee – has had the money-back offer for almost one year, Qianjiang Evening News reported.

Only once has the money been claimed in that time – and that was because a diner had taken the banknote from a waitress as a joke, owner Zhu Xiaojian said.

He came up with the idea of the money offer from a popular Chinese entertainment television show Running Man, which includes a section called, “Name-tag ripping”, where contestants vie to grab the most name tags from their rivals’ clothes.
